> The delay of ipc.Client.handleConnectionFailure() that causes the client to 
> block and wait is hard coded at 1 second; any interruption of the thread is 
> treated as a shortening of the delay.
>       // otherwise back off and retry
>       try {
>         Thread.sleep(1000);
>       } catch (InterruptedException ignored) {}
>       
> 1. this delay could be configurable; different clients may wish to retry 
> more/less often. or at a slightly different rate than their peers.
> 2. interrupting the thread may imply the client has been requested to 
> terminate -this could be handled by declaring failure early, rather than 
> continuing to retry until the retry count is exceeded.
